A Florida school district is considering disciplinary action against a high school student who created a racist poster to ask his girlfriend to the prom, the Sarasota Herald-Tribune reported Monday.

"If I was black, I'd be picking cotton, but I'm white, so I'm picking u 4 prom," read 18-year-old Noah Crowley's sign, according to the Sarasota County school district, the newspaper reported.

Outrage grew as an image of the poster made its way through the social-media ecosystem: screen grabbed from Snapchat and reposted to Twitter.

Parents of Riverview High School students received a robocall on Monday morning rebuking the student's action.

"[The post] was racial in nature and administration became aware of it last night," said Riverview acting principal Kathy Wilks in the call to parents. "Many who saw the post are understandably upset with its contents as well as the subsequent commentary to the post. Riverview High School absolutely does not condone or support the message conveyed in this post."

On Tuesday, Crowley released an apology through a Tampa public relations firm.

"I want to sincerely apologize if I have offended anyone with the picture going around," the statement read. "That was not my intention. Anyone who knows me or ***** [name redacted] knows that that's not how we truly feel. It was a completely joke and it went too far. After reading the texts and Snapchat's I truly see how I have offended people and I'm sorry."
